Abstract
The utility model belongs to the technical field of the bearing is made, a thrust bearing is proposed. The thrust needle roller bearing is provided with a bearing inner ring and a bearing outer ring; the outer diameter surface of the bearing inner ring is a conical surface with inner ring flanges at two ends; the inner diameter surface of the bearing outer ring is a conical surface with outer ring flanges at two ends; the outer ring flange on the bearing outer ring is arranged corresponding to the inner ring flange on the bearing inner ring; the inner diameter surface of the bearing outer ring is consistent with the inclination direction of the outer diameter surface of the bearing inner ring; and a plurality of conical rolling bodies which are uniformly distributed along the circumference are arranged between the bearing inner ring and the bearing outer ring. The utility model provides a bearing can not the drawback of axial atress, widened bearing's use field greatly.
Description
Technical Field
The utility model belongs to the technical field of the bearing is made, it is a thrust bearing very much to indicate.
Background
In the manufacturing industry, in order to design mechanical equipment with small volume, light weight and compact structure, a needle bearing is often selected, and the needle bearing consists of a slender cylindrical rolling body and a very thin outer ring or inner ring, so that the structural size of the mechanical equipment is greatly reduced in the radial direction of the bearing, but the rolling body in the conventional needle bearing is of a cylindrical structure with two ends being equal to circles, so that the needle bearing cannot be used in the occasion with axial stress, and the use field of the needle bearing is greatly limited.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the present invention provides a needle roller thrust bearing.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a thrust needle bearing is provided with a bearing inner ring and a bearing outer ring; the outer diameter surface of the bearing inner ring is a conical surface with inner ring flanges at two ends; the inner diameter surface of the bearing outer ring is a conical surface with outer ring flanges at two ends; the outer ring flange on the bearing outer ring is arranged corresponding to the inner ring flange on the bearing inner ring; the inner diameter surface of the bearing outer ring is consistent with the inclination direction of the outer diameter surface of the bearing inner ring; and a plurality of conical rolling bodies which are uniformly distributed along the circumference are arranged between the bearing inner ring and the bearing outer ring.
And rolling element retainers for placing a plurality of conical rolling elements are arranged between the inner ring flanges at the two ends of the bearing inner ring and the outer ring flanges at the two ends of the bearing outer ring.
The utility model provides a pair of thrust bearing changes the cylinder rolling element of the inside both ends isocircular of rolling element bearing into the unequal cone rolling element in both ends, has solved the drawback that bearing can not axial atress, has widened bearing's use field greatly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the bearing comprises a bearing inner ring, 2 conical rolling bodies, 3 rolling body retainers, 4 inner ring flanges, 5 bearing outer rings and 6 outer ring flanges.
Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in fig. 1, a needle thrust bearing has a bearing inner ring 1, a bearing outer ring 5; the outer diameter surface of the bearing inner ring 1 is a conical surface with inner ring flanges 4 at two ends; the inner ring flange 4 is used for preventing the rolling body from falling out; the inner diameter surface of the bearing outer ring 5 is a conical surface with outer ring flanges 6 at two ends; the outer ring flange 6 is used for preventing the rolling body from coming off; the outer ring flange 6 on the bearing outer ring 5 is arranged corresponding to the inner ring flange 4 on the bearing inner ring; the inner diameter surface of the bearing outer ring is consistent with the inclination direction of the outer diameter surface of the bearing inner ring; and a plurality of conical rolling bodies 2 which are uniformly distributed along the circumference are arranged between the bearing inner ring 1 and the bearing outer ring 5.
And rolling element retainers 3 for placing a plurality of conical rolling elements are arranged between the inner ring flanges at the two ends of the bearing inner ring and the outer ring flanges at the two ends of the bearing outer ring, and the rolling element retainers are used for isolating and restraining the conical rolling elements 2 to prevent the rolling elements 2 from generating friction collision.
